OBJECTIVE: To provide for an expedited bidding process to obtain the construction work order(s) to proceed with expedited dredging and clearing of Clam Pass and approve necessary budget amendments. CONSIDERATIONS: On December 11, 2012, the Board of County Commissioners (BCC) clarified and reaffirmed that the Pelican Bay Services Division has the respons'bility for advising the County on dredging and maintaining Clam Pass and for managing suc activities for the County. On January 8, 2013 (Item 10R) the Board of County Commissioners decl ed that the recent closure of Clam Pass constituted a valid public emergency requiring dredging f the Pass as soon as practicable. Services related to the permitting, surveying, engineering and onstruction phase engineering services were authorized and include: Task Firm Cost Project Surveying Agnoli, Barber and Brundage (ABB) $20,900 • Original Amount: 18,400 • Change Order#1 Pending: 2,500 Permits and Management Turrell, Hall and Associates 28,000 Plan Design, Plans and Humiston and Moore 23,650 Specification Development Construction Services Humiston and Moore 52,710 Construction drawings were delivered to the County Manager's Office on i 'day, January 18, 2013, by Humiston and Moore. Approximately 20,000 cubic yards of sang will be removed from Clam Pass and used for inlet restoration and beach renourishment; ,ervices are to be performed with mechanical equipment. The Pelican Bay Advisory Board is si heduled to review the plans and make a recommendation to the Board of County Commis&•ners following a special meeting on Monday, January 21, 2013. Purchasing staff have identified options to obtain construction prices for the project and have been in contact with a number of firms on two Board approved contracts, incl •ing: • The five (5) firms on contract 08-5011 Underground Utility Contr.ct are licensed to perform this type of work and may submit a"total unit-price" for the p oject; and • The three (3) firms on contract 11-5673 Disaster Debris Removal & Disposal Services have indicated that they are capable of coordinating and directing t e activity through subcontractors and may submit a"cost-plus"price proposal for the pry i ect. Add On Item 11H January 22,2013 Staff recommends that these contracted firms be invited to attend a project "p e-bid meeting" as soon as practicable; the meeting will be coordinated by the Purchasi g Department in conjunction with Humiston and Moore. Once prices are received (5 – 7 days .fter the "pre-bid" meeting), Purchasing staff and Humiston and Moore would review, reco end and request approval from the County Manager to approve the issuance of work order() under the Board approved contract terms and conditions. FISCAL IMPACT: At its January 8, 2013 meeting the Board authorized ding for design, permitting and construction phase services. The budget for those services i• included in TDC Beach Renourishment/Pass Maintenance Fund (195) under project 88032. T e final cost of the construction phase will be known when the construction work order(s) ar; approved by the County Manager. A budget amendment appropriating reserve funds from TDC Beach Renourishment/Pass Maintenance Fund (195) for the construction phase the Clam Pass dredging project will be necessary. LEGAL CONSIDERATIONS: This item has been reviewed and approv d by the County Attorney's Office, is legally sufficient for Board action and only requires a majority vote for approval—SRT. GROWTH MANAGEMENT IMPACT: There is Growth Management mpact associated with this item. RECOMMENDATION: That the Board of County Commissioners approves the expedited solicitation process for the construction dredging of Clam Pass and directs tho County Manager to issue contract work order(s) to the firm(s) who submits the lowest responsive price(s) for the Clam Pass project and approve necessary budget amendments.

Such management requires prudent caution when addressing excavation of stream bed or tidal channels, as these areas are contiguous with and support wetlands habitats and wildlife that utilize both the aquatic area and its wetlands. The Calusa Group appreciates that the engineering firm put effort into the draft construction/excavation plans and these plans should be discussed fully as a potential alternative for long term management. Calusa Group will not object to the draft for entrance cuts 0+00 to 3+64.5 from the Mean High Water Line to the submerged bottom - which is roughly 202 sq. ft in those cross sections, but do object to the new element of the designed channel to now include extension into the Gulf of 400 ft west of station 0+00 We do suggest that the excess unconsolidated sand which has moved ashore from the ebb shoal should be moved out of the path of the area to be excavated in advance of such excavation and should not be included in the dredge cut design. Further, the 1/2 foot over dredge is a new element that should be removed as there is no ecological justification to add another half foot to allowed dredged depth Calusa Group objects to the new element of this draft for a dredged channel to excavate Clam Pass middle area from shoreline to shoreline which eliminates tidal flat wetlands and increases the loss of benthic habitat. Calusa Group objects to the new element of enlarged widths in Segment C. • ; ( C. ) P(fie 2 ") Recommendations from Sierra Calusa Group on the Draft Plans of 1/17/13 1) Eliminate the Westward expansion of the design which extends 400 ft into the Gulf from station 0+00. 2) Eliminate the 1/2 foot over dredge from all stations. 3) Do not exceed the widths in Segment B that were authorized in the prior ten year permits. Rather than enlarging widths in this area, Calusa Group recommends that these widths be reduced wherever possible. 4) Do not exceed the widths in Segment C that were authorized in the prior ten year permits. Rather than enlarging widths in this area, Calusa Group recommends that these widths be reduced wherever possible. 5) For the immediate need to reopen Clam Pass - whether by mechanical excavation or barge operated dredging - Calusa Group recommends that only Segments A and the part of Segment B which are choked by sand would be excavated at this time and overall maintenance dredging limits require further discussion from affected stakeholders and user groups before proceeding with plans for those segments. Please consider these recommendations in good faith for the health and sustainability of the Clam Pass - Clam Bay NRPA. Thank you for the opportunity to participate in your discussions.

Mr. Humiston should clarify t e issues discussed below. 1 . On pages 2 & 3: What is the unlabeled segment to the left of Segment A? When and why would this segment be utilized? 2. What does "Over Depth Allowance" mean? It cannot mean a "margin of error of 0.5 ft deep" because according to the "Dredge Station Control and Volumetric Information" Table on the last page, the estimated volume of approximately 21 ,000 cubic yard of sand can only be obtained by including the "Over Depth Allowance". Consequently, the actual dredge depth for Segment A is (— 6.3 ft. NAVD88 or - 5.0 ft. NGVD). For segment B, the actual dredge depth is (- 5.8 ft. NAVD88 or - 4.5 ft. NGVD). For Segment C, the actual dredge depth is (- 5.3 ft. NAVD88 or — 4.0 ft. NGVD). These are the same depths as in the prior authorized 1998 Dredging Permit, and the Coastal Zone Management (CZM) PBSJ permit application, with the exception of the depth in Segment A which is 0.5 ft less in the Draft H&M Construction Plans. 3. The proposed dredge width in Segment A is 45 ft (15 ft wider than the authorized 1998 dredge permit), as agreed upon by Ken Humiston & MAG President Ted Raia, in the presence of Commissioner Hiller. However, the dredge widths of a number of stations in Segments B & C (listed below) have been enlarged; this was not discussed or agreed to. They are even wider than the illicit 2007 (80 ft. wide) dredge design, as well as the CZM PBSJ permit application. What is the purpose of enlarging these stations? Kathy Worley, Senior Scientist at the Conservancy has consistently objected to dredging too close to the mangrove roots as this practice will damage the mangroves during and after excavation. Furthermore, this practice will unnecessarily reduce benthic habitats needed by aquatic fauna and flora to survive and flourish in Clam Bay. The dredge widths of the following stations have been enlarged from the CZM PBSJ permit application, and the prior authorized 1998 Dredge Permit.

Summary Conclusions It appears that the Draft H&M Plan, as stated in the Executive Summary of the Add On Item 11H for the 1/22/13 BCC Meeting, is designed to meet th objective of obtaining approximately 20,000 cubic yards of sand for inlet resto ation and beach renourishment. According to the "Fill Template Information" Table on the last page of the Draft Plans, 5280 cu. yd. of sand can be placed on locations - 40, and R- 40+725 north of the Pass; 24,000 cu. yd. of sand can be placed o locations R- 42 and R- 44 south of the Pass. This plan talks a lot about sand volumes and renourishment, but nothing about dredging to maintain health of the eco-system. If this draft plan is to be used; clear statements must be included 'n the PBSD dredge permit application that this design will only be used to add ess the critical condition presently existed in Clam Pass, and not be used for fut re maintenance dredging. This H&M Plan has expanded the scope of the prior authorized 1998 dredge permit instead of reducing it. It is uncertain that the regulatory agencies would approve this plan quickly. The Nation-wide Permit 27 states that applications should not differ from a prior permit (the 1998 permit) used as a basis. This plan does deviate significantly, and environmental and conservation groups may object to it. ! if4iA.,,-) ?Clic_ 34.c 3 NOTE: The recent survey conducted by Agnoli, Barber, & Brundage from January 3 to 11 , 2013, shows that in Segments B & C, the channel depths and wid hs remain quite constant at approximately — 4 ft NGVD, and 25 to 40 ft wide, indic ting the Pass is at its equilibrium condition. Segment A is completely filled in with an ddition of 2 ft of sand. Undoubtedly, Segment A does need to be dredged to allow for tidal flushing for the health of Clam Bay, as well as for fish to enter and exit the lestuary, but let's not over-dredge Segments B & C for the purpose of accumulating for mining sand. As stated in Humiston & Moore Bathymetric Monitoring Report # 9, p. 11, November 2008; "It should be understood that Segment C is dredged to a much larger channel flow cross section than the entrance channel, so that a substantial amount of sand can accumulate in Segment C before it begins to adversely affect inlet hydraulics. This area is designed to act as a deposition basin for sand carried into the inlet and becomes a source of sand for beach renourishment when inlet dredging becomes necessary." Accumulating sand and dredging for renourishment of adjacent b4aches should no longer be a consideration of Clam Pass maintenance dredging. Linda Roth Montenero 254-8889
